MM54HC280数据手册TI中文资料规格书

描述 Description

General Description
The MM54HC280/MM74HC280 utilizes advanced silicon gate CMOS technology to achieve the high noise immunity and low power consumption of standard CMOS integrated circuits. It possesses the ability to drive 10 LS-TTL loads.
This parity generator/checker features odd/even outputs to facilitate operation of either odd or even parity applications. The word length capability is easily expanded by cascading devices. The 54HC/74HC logic family is speed, function, and pinout compatible with the standard 54LS/74LS family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground.
